title: 2-(4-Fluoro-phen-yl)-5-iodo-7-methyl-3-phenyl-sulfinyl-1-benzo-furan.
abstract: In the title compound, C21H14FIO2S, the dihedral angles between the mean plane [r.m.s. deviation = 0.007 (1) Å] of the benzo-furan fragment and the pendant 4-fluoro-phenyl and phenyl rings are 3.66 (7) and 82.37 (6)°, respectively. In the crystal, mol-ecules are linked by pairs of C-H⋯I hydrogen bonds into centrosymmetric dimers, which are further packed into stacks along the b axis by C-H⋯O hydrogen bonds. In addition, the stacked mol-ecules exhibit inversion-related S⋯O contacts [2.9627 (14) Å] involving the sulfinyl groups.
